Lindsay Lohan's dad Michael threatens her staff

LINDSAY Lohan's dad has publicly threatened a member of her staff after an unflattering photo of the actress was taken while partying in Brazil last week.

Michael Lohan wrote an open letter to her booker Mike Heller, reports RadarOnline.

Mr Lohan stated he would hold Heller "personally responsible" if anything happened to his daughter.

"I am telling you now if you are with Lindsay in Rio or you booked it, and anything happens to my daughter, I am holding you personally responsible," he wrote.

"Judging from what has happened to in the past, and the way she looks down there from the pictures in the media, it’s not a good thing. If you have anything to do with her being there, its on you. Count on it."

Mr Lohan had mistakenly identified his daughter's location. The actress, 26, was in a Sao Paulo nightclub when she was photographed sitting on the floor under a DJ table in the early hours of the morning.

She reportedly arrived at the club around 2am Thursday surrounded by security guards and headed straight to the DJ booth.

The actress spent the evening talking with friends while sitting on the ground. She sipped on coconut water and did not want her picture taken by local fans.

She was reportedly paid $100,000 to attend a clothing line launch party at the club.
